Pareidolia

Posted by on August 25, 2009 No comments

The Best of Wikipedia is a continually updated collection of some of the most interesting Wikipedia articles. Here’s one from yesterday:

Pareidolia – Pareidolia is a psychological phenomenon involving a vague and random stimulus (often an image or sound) being perceived as significant. Common examples include seeing images of animals or faces in clouds, the man in the moon, and hearing hidden messages on records played in reverse. There have been many instances of perceptions of religious imagery and themes—in 1978, a New Mexican woman found that the burn marks on a tortilla she had made appeared similar to the traditional western depiction of Jesus Christ’s face. Thousands of people came to see the framed tortilla. Pareidolia is a type of apophenia.

Cocksure

Posted by on July 24, 2009 No comments

Malcolm Gladwell’s new article, Cocksure, is about the psychology of overconfidence. In it he postulates that the brashness of experts caused the current financial crisis.

Since the beginning of the financial crisis, there have been two principal explanations for why so many banks made such disastrous decisions. The first is structural. Regulators did not regulate. Institutions failed to function as they should. Rules and guidelines were either inadequate or ignored. The second explanation is that Wall Street was incompetent, that the traders and investors didn’t know enough, that they made extravagant bets without understanding the consequences. But the first wave of postmortems on the crash suggests a third possibility: that the roots of Wall Street’s crisis were not structural or cognitive so much as they were psychological.

Married to the Eiffel Tower

Posted by on March 24, 2009 No comments

Married to the Eiffel tower is a BBC documentary about objectophilia, a pronounced sexual desire toward particular inanimate objects.

Erika La Tour Eiffel, like Eija-Riitta Berliner-Mauer – the woman who married the Berlin Wall, is an … “objectum sexual”, people who fall literally in love with buildings and objects. They have sex and relationships with them; their passion as ardent as any human relationship.

The documentary subjects discuss sexual fantasy with objects throughout the documentary so use your discretion. This is part 1 of 7.

Hit play or watch Married to the Eiffel Tower on Youtube.

Part 2, part 3, part 4, part 5, part 6, part 7.

Why we think it’s OK to cheat and steal (sometimes)

Posted by on March 17, 2009 No comments

Listen to Dan Ariely’s talk, presented in February 2009 at the TED conference, about his experiments in predictable irrationality. He explains how bugs in our moral code make us think it’s okay to cheat or steal sometimes but not others.

The Thatcher Effect

The Thatcher effect is the phenomenon in which it becomes difficult to detect local feature changes in an upside down face, despite identical changes being obvious in an upright face.

Here it is, in video format:

Subliminal Ringtones

Posted by on February 24, 2009 No comments

I can’t express the level of scepticism I feel over this Discovery Channel clip claiming that subliminal ring tones can affect the way our minds think and even the way our bodies grow.

Hideto Tomabechi made headlines in June 2005 when he started selling a ring tone that he claims could make a woman’s breasts grow larger just by listening to it.

If ring tone breast enhancement smacks of gimmickry, the theories behind it are taken very seriously indeed. Over the last ten years, Dr. Tomabechi has been lecturing on how to apply his mind manipulating techniques to the threat of terrorism.

His services have been in demand ever since March 1995 when members of the Aum Shinrikyo doomsday cult released a nerve gas called sarin into the Tokyo Subway System which injured 5000 people and killed 12. Dr. Tomabechi was asked by the Japanese police to deprogram some of the brainwashed members of the cult by applying his “sound” theories.

Hit play or watch at YouTube.

For the record, there have been no scientific studies which demonstrate anything remotely close to subliminal commands influencing motives. It all boils down to the fact that subliminal messages designed to change behaviour DO NOT WORK.

Sine-wave Speech

Posted by on December 9, 2008 No comments

First developed by Robert Remez and Philip Rubin at Haskins Laboratory, Sine-wave speech is a form of artificially degraded speech. Much like the “aha” moment one gets when one listens to music backwards with a suggested lyric showing, the sine-wave speech is easily recognizable once the listener has been primed.

Listening to the sine-wave speech sound again produces a very different percept of a fully intelligible spoken sentence. This dramatic change in perception is an example of “perceptual insight” or pop-out. We have argued that this form of pop-out is an example of a top-down perceptual process produced by higher-level knowledge and expectations concerning sounds that can potentially be heard as speech.

I picked up on a few of the lines without checking first, and it got easier as I went along.

Try the examples yourself at Sine-wave speech.

Quirkology – The Missing Piece

Posted by on September 17, 2008 No comments

See if you can figure out how psychology professor Richard Wiseman creates space for the missing piece. I have to admit, even though I’ve seen tricks like this before, it took me 3 or 4 times through to figure it out completely.

Teaching of Psychology

Posted by on July 15, 2008 No comments

Tom Stafford, a member of the Adaptive Behaviour Research Group in the Department of Psychology at University of Sheffield, recently presented the keynote speech at the annual conference of the Association for the Teaching of Psychology at Lincoln in the UK. He talked a little bit about the priming that can occur when you load up my backmasking site. He was kind to present the topic using this slide.

Thanks Tom… you made my day.

Research Digest wrote up an interesting summary of Tom’s keynote talk.

Amazing Audio Illusion

Posted by on June 26, 2008 No comments

Play this audio clip again after it finishes and hear it continue to “creep up”.

See Wikipedia’s entry on Shepard Tone for the full scoop.

A Shepard tone, named after Roger Shepard, is a sound consisting of a superposition of sine waves separated by octaves. When played with the base pitch of the tone moving upwards or downwards, it is referred to as the Shepard scale. This creates the auditory illusion of a tone that continually ascends or descends in pitch, yet which ultimately seems to get no higher or lower.
